Abstract
The present invention relates to a method for manufacturing an optical element including a layer comprising anisotropic optical function and alignment capability. The layer is formed from a composition comprising polymerizable liquid crystals and one or more photo-orientable substances. Alignment on top of the layer is achieved by exposure to linearly polarized light.
Claims11
A layer structure comprising a PLCPO layer, which has an optical anisotropic property and which has alignment capability on its surface, wherein at least in one area the alignment direction provided by the PLCPO layer is different from the liquid crystal orientation in the PLCPO layer just beneath the upper surface of the layer.
A composition comprising polymerizable liquid crystals and a photo-orientable substance, wherein the percentage by weight of photo-orientable substances is less than 5%, less than 1 wt % or even less than 0.1 wt % and the photo-orientable substance comprises fluorinated and/or siloxane moieties and/or is a polysiloxane,
